Hi guys. I have a Bitty (Casey) that I found at a Salvation Army a while ago with blue marker on her face and left hand. (I think I only paid 2 bucks for her!) Anyway, I tried the Mr. Clean scrubber thing and it didn't work. I thought I heard something about using Oxy 10 or something? Please help me out! She is such a cute bitty, and even though the blue matches her outfit, I don't want it on her skin! Thanks!
